Big Bass Xmas Extreme at Don Casino: Know the game before you spin
Pragmatic Play's 5x4 fishing game uses a pick-a-box round before free spins, 96.07% RTP, high volatility where wins land bigger but less often.
Big Bass Xmas Extreme: a high-volatility Christmas fishing slot
Big Bass Xmas Extreme: grid and money symbols
Big Bass Xmas Extreme landed in November 2024 as a 5-reel, 4-row fishing game from Pragmatic Play with a Christmas theme. The 10 paylines run left to right across a winter-themed grid. Money symbols appear as random values on each spin, ranging from 0.2x up to 1000x your bet. High volatility means wins arrive less often but can be substantially larger. The game layers fishing mechanics with seasonal imagery to create a distinct festive setting.
Consider your budget before the ante bet
This slot suits players chasing bigger rewards and comfortable with longer gaps between wins. The Ante Bet feature raises your stake by 50 percent to boost winning chances, while Buy Free Spins costs 100 times your bet—ideal if you want to enter the bonus round immediately. Players with smaller budgets or those preferring frequent small wins will find the high volatility and premium buy-in less compatible with their style.
How Fisherman Wilds reshape your free spins
The Free Spins round defines how a session unfolds. You start with 10 spins but first face a Pick a Box phase in a 3D Christmas room, selecting gifts to unlock extras: more spins, guaranteed money symbols each round, Fisherman Wilds that collect all visible money, or removal of lower-value money symbols. During the spins themselves, each Fisherman Wild collects all money on screen, and every fourth collected Wild adds 10 more spins while escalating a multiplier that climbs from 2x through to 50x.

Play your first round
How much can you wager?
You set your bet between A$0.10 and A$375 before each spin. The 5x4 grid holds ten fixed paylines reading left to right. Once you confirm your stake, the reels turn.
When do symbols pay?
Matching symbols pay across the ten paylines when three or more land from left to right. Most symbols need three matches; Fisherman Backpack pays from just two. Money values appear randomly on special symbols each spin.
What appears on the reels?
Reels stop and the grid shows what landed. Money symbols hold random values from 0.2x to 1000x your bet. A collect event might trigger, multiplying all Money symbols by 1x to 50x before payout.
Scatter unlocks the bonus
Ten Free Spins begin when you land a Scatter. Before the bonus starts, a 3D room appears where you pick gifts to add spins, guarantee Money symbols, place Fisherman Wilds or remove low Money values.
How do you stay in control?
Before playing, set limits in your account to control your session: a deposit cap, a loss limit, session time reminders or self-exclusion. Don Casino supports Gambling Help Online, Lifeline Australia and BetStop.

How playing for money works
What you cannot know before you spin
Don Casino shows you the game's odds and features, not its outcome. Random results are built into slot play.
When the bonus comes
The bonus round arrives without a schedule. No pattern tells you when Pick a Box and Free Spins will start, no matter how many base game spins you play.
Can your session beat the odds?
One session might win you money; another might not. The RTP of 96.07% describes results across millions of spins, not what happens in your session.
Maximum win versus typical wins
The maximum win of A$3,750,000 sits at the top of the payable range but lands far less often than smaller wins. Reaching it is rare.

Gambling should never cost more than you can afford
Your spending limit matters. Decide how much you can afford to lose before your first spin. Stick to that amount and treat the cost of play the same as any other entertainment expense.
Wins are reasons to stop. Stop playing when you reach your limit, even after a win. Step away and decide whether to play another session only after time has passed.
Can account limits protect me? Before Before you play, use your account deposit limit and loss limit. These tools cap your spending and prevent sessions from costing more than planned.
Step back when it matters. If the game stops being enjoyable or you worry about your play, take a break. Use self-exclusion through BetStop or contact Gambling Help Online for support.
